By using this commit on my shard i have one strange bug - every 1-2 days bit by bit all scripts freezing. Connecting still work, but only it. And this continues untill i restart server. I coud not find trigger of this, even with dumps, or live debugging with studio - all threads working, none errors, exceptions or console warning. Scripts thread often entering in this block ( scripts_internals.cpp : 213) if it matters
